MD5SUM is a very simple program to display checksums of all the files in a directory. It assumes that the directory to start the search from is 'C:\Program Files\NDW'.
Download the file and simply double click it.
It does not modified, or use, the registry, neither are any files writen to your hard disk when the program is run.
To use it smply press 'Select Dir' and choose a directory, the checksums of all the files in that directory will be displayed.
You may save these to a file if you wish.
MD5SUM is provided under the GPL licence so the Visual C++ 6.0 source code is also available.
